How to Choose the Perfect Double-Walled Glass

By the Joybuy team, our in-house experts

Does your coffee go cold before you can even take a sip? Tired of the condensation rings your iced tea leaves on your furniture? The double-walled glass is the elegant and practical solution to these everyday annoyances. Far more than just a stylish object, its ingenious design literally transforms your coffee (or tea!) break.

In this guide, we'll break down the benefits of these glasses and present our selection of the best models. Our goal: to help you find the one that will perfectly suit your drinks and your daily routine.

How to Choose Your Double-Walled Glass

Before you fall for a particular model, let's review the key criteria that will make all the difference in your daily use.

1. Material: Borosilicate Glass, the Gold Standard

Nearly all quality thermal glasses are made from borosilicate glass. And it's no coincidence: this material boasts numerous advantages:

• Thermal Shock Resistance: It withstands sudden temperature changes with ease, reducing the risk of breakage when you pour a boiling liquid into a cold glass.
• Lightweight and Clear: Both sturdy and surprisingly light, it offers crystal-clear transparency that enhances the colour of your drinks.
• Preserved Flavour: It is completely neutral and will never alter the flavours of your coffee, tea, or fruit juice.

2. Capacity and Shape: A Glass for Every Drink

Capacity is obviously a key criterion. An espresso lover won't have the same needs as a latte macchiato fan.

• For espresso (approx. 80 ml): A small double-walled espresso cup is perfect. It preserves heat and concentrates the aromas of this short coffee.
• For long coffee or tea (200 to 300 ml): A medium-sized double-walled cup is the ideal all-rounder for daily use.
• For milky drinks (300 to 450 ml): A tall latte macchiato glass is essential for admiring the drink's layered effect.
• For cold drinks: A large insulated glass will keep your juices, smoothies, or beers perfectly chilled, without leaving unsightly condensation marks on the table.

3. Ergonomics and Care: With or Without a Handle?

The choice between a model with or without a handle is primarily a matter of taste. Handle-free glasses are appealing for their sleek, minimalist design, as the double wall is sufficient to protect your hands from the heat. Those with handles provide a more traditional and secure grip, especially for larger capacities.

Also, remember to check the manufacturer's care recommendations. Most recent models are dishwasher-safe, a real daily convenience!

Our Recommended Double-Walled Glasses

To help you decide, our editorial team has selected three models that caught our eye, each for a specific use case.

1. De'Longhi Latte Macchiato Glass Set (DLSC312), 330 ml

Why It Stands Out

This De'Longhi set is for lovers of milky drinks. With their 330 ml capacity and slender shape, these glasses are perfect for crafting a flawless latte macchiato and admiring the layers of milk, coffee, and foam.

Highlights

• Perfect Insulation: Keeps your drink hot for longer, while the outside remains comfortable to touch.
• Meticulous Finish: The borosilicate glass is hand-blown for impeccable clarity and quality.
• Ideal Capacity: The 330 ml volume is perfectly calibrated for milky drinks.
• Easy to Clean: Dishwasher-safe for hassle-free maintenance.
• Zero Condensation: No more rings on the table!

Who Is It For? For proud owners of coffee machines (especially De'Longhi) who want to elevate their latte macchiatos and other gourmet creations.

2. Bodum BISTRO Set of 2 Thermal Glasses with Handle, 450 ml

Why It Stands Out

The BISTRO model from Bodum combines a generous capacity with the practicality of a handle. At 450 ml, it's perfect for long tea sessions, comforting hot chocolates, or even a cold beer. Its versatility makes it a must-have.

Highlights

• Large 450 ml Capacity: Ideal for soups, smoothies, large coffees, and other XXL drinks.
• Ergonomic Handle: Ensures a comfortable and secure grip.
• Ultra-Versatile: Safe for the dishwasher, microwave, and even the oven (within the temperature limits specified by the brand).
• Effective Insulation: Maintains temperature without burning your fingers or leaving condensation marks.
• Quality Craftsmanship: Made from mouth-blown borosilicate glass.

Who Is It For? For those looking for a large, all-purpose mug that's comfortable for everyday drinks (hot or cold) and who swear by the secure grip of a handle.

3. Bodum PAVINA Set of 6 Thermal Glasses, 80 ml

Why It Stands Out

The iconic design of the Bodum PAVINA, here in an 80 ml size tailored for espresso. Sold as a set of six, it's ideal for serving coffee when you have guests. The levitating effect of the espresso is stunning and beautifully showcases the crema.

Highlights

• Espresso Size (80 ml): The perfect size for a single or double shot.
• Set of Six Glasses: Ideal for outfitting your kitchen or for entertaining.
• Iconic Design: A sleek, award-winning shape that enhances the drink.
• Thermal Insulation: Keeps the espresso hot without burning your fingers.
• "Levitating" Effect: Your coffee appears to float in the glass, a spectacle in itself.

Who Is It For? For espresso purists who want to enjoy their coffee properly and share the ritual with their guests.

Frequently Asked Questions About Double-Walled Glasses

1. Are double-walled glasses microwave-safe? It depends on the model. Some, like the Bodum BISTRO we feature, are compatible. For many others, it's not recommended: the intense heat can damage the seal between the two walls. The golden rule: always check the manufacturer's instructions before placing a thermal glass in the microwave.

2. What's this little silicone dot under my glass? Don't worry, it's not a defect—quite the opposite! It's a hydrophobic silicone valve. Its role is to equalise the air pressure between the two walls (which varies with the liquid's temperature). This clever mechanism prevents the glass from cracking under pressure while ensuring a perfect seal.

3. How can I prevent condensation from forming between the two walls? If condensation forms on the inside, it means the seal is no longer effective. To ensure a long life for your glasses, handle them with care: avoid impacts and overly sudden temperature changes (like pouring ice water into a glass straight from the dishwasher). And of course, always follow the brand's cleaning instructions.
